2020 non bose DSP... and door chime help

[Russ757]

In the process of upgrading my non bose system to something more ear friendly. 

 

Currently 

Skar tx65/69, kenwood kfc 2.75; all stock HU powered, and RF P300 self contained amp fed from and LC2i. No real issue except want something better

 

Recently ordered

2 JL 10w

RF t400x4 (doors) and t750x1 (subs to 4 ohms)

infinity reference 6x9/6.5, keeping the kenwoods in the dash

integration harness from John Adams (not llj)

 

Figured pretty basic install but wondering about two things

 

If I keep the Lc2i, Ill need to y split the HP to the 4 channel amp as it only has the one set of outputs. Not a deal breaker but not ideal. But now considering a DSP instead. For those who installed one, what did you go with but more importantly, how did you convert to the low level input most seem to take? I looked at audio control and saw the 608 accepted high/speaker level inputs but trying to stay a bit cheaper. The rest seem to take RCA.. (was looking at the RF dsr1). Are there other high level input DSP?

 

Also, and more in general.. I keep hearing that once you amp, the chimes become ongodly loud. At first was like, meh whatever but as I keep thinking through the build... With the integration harness, I will be using the stock wiring through the molex connector to the door speakers running off the 400x4.

I’m in a similar situation as yourself on the audio upgrade. I’ve got the same non-Bose system (2020 Custom) as well.

 

I added front component sets and coax speakers in the rear doors (all Infinity Reference speakers). Stock HU feeding an LC7i into a Kicker Key 200.4 amp. The amp has DSP and time alignment built in.

 

Sounds mediocre at best. Really muffled actually. For the harness, I found one on crutchfield and made my own loop back. Very simple actually. Fed front channels into the LC7i and left the rear door channels alone to feed the rear doors of the stock HU power (not amp’d). The idea was to run the components in a bi-amped config (4 channels feeding front door speakers and new dash tweets all on separate channels) to take advantage of the amps time alignment capabilities. 
 

Issue is the amplification of chimes and signal sounds. These come in from the front channel HU output. In my config I had to turn the gain at the LC2i down to limit amping those sounds. Problem is it’s limiting the regular audio signal at the same time. I’ve ran it this way for a while since it’s a PITA to remove the rear seat and I needed my truck back (ran out of time to F with it). Hoping someone with more experience than myself or with a similar config has solved this issue can weigh in and help yourself and me. I feel my issue is a tuning problem or an LC2i config issue. 
 

Best of luck. Following your build.
